Jewellery for niece's 21st HELP

[onlyme2014]

Hello, I'm looking for a really nice piece of jewellery for my niece's 21st. I would be really grateful for any advice on brands I should look at please.

She likes Pandora, Tiffany, Annie Haak etc. I have an 11yr old boy so I have no idea! TIA

I got all three of DH's nieces items from Tiffany which they loved, the oldest got a necklace and the twins bracelets.

Thanks fivegomad, I'll have a look online.

I think Tiffany is a bit naff nowadays, sorry.

Would she like Alex Monroe?

DD had Tiffany for her 21st from DB and SIL - she loves it. I quite like Pandora, but I wonder if it's too 'of the moment' - for her 21st it would be lovely to have something she could wear forever.

Also have a look at Marni.

It's more costume jewellery but she might love it now and look back on it fondly

Net a Porter has lots of fashion jewellery, not really classic though

I bought my niece stack rings from daisy in her initials - she really liked them

Thank you so much for all the ideas! I've just come back to see all your messages. I will look at all of them.

Have a look at the Paloma Picasso collection for Tiffany, I got a ring from it from my mum and dad for my 18th two years ago and never take it off!

I always get complements for it and its a bit more unusual than the traditional Tiffany collection that everyone seems to have.

Thanks for all the lovely suggestions. I finally ordered an Oliver Burton watch (I know she likes them and had forgotten), three Alpha rings from Daisy and a necklace from Stella & Dot. It was all so lovely!
Hope she likes it all now.
Thanks again.
